  1. Article: Recent Approaches To 'Super-Resolution' Microscopy Utilizing Camera Detection 12/10/2008
    In this article, we describe some novel camera-based approaches which enable the cell biologist to break through the diffraction-limited spatial resolution of classical light microscopy, enabling much finer sub-cellular detail to be elucidated than was previously possible. The role of ultra-sensitive, rapid readout cameras is proving central to the ability to drive these methods faster, particularly critical to realize the goal of super-resolution imaging of dynamic processes in living cells.
  2. Temperature Vs. Performance: White LEDs And Fluorescent Lamps Have A Lot In Common 12/9/2008
    White LEDs have become a rising star for both conventional illumination and machine vision lighting. There are several methods to create white light with LEDs, but the most popular and cost effective technique at this time, is the “blue LED plus yellow phosphor” approach. It is the use of the phosphor that causes the white LED to mimic the fluorescent lamp.

  6. Visible And Non Visible Imaging Techniques 9/30/2008
    The field of industrial microscopy has evolved from simple bright-field on-axis imaging to that of nonvisible and confocal-based technologies. Bright-field is a resolution-limited technique that uses on-axis illumination and imaging to form the image, typically with visible light.

    The field of industrial microscopy has evolved from simple bright-field on-axis imaging to that of nonvisible and confocal-based technologies. By combining techniques, manufacturers can conduct fast, nondestructive measurement and analysis functions. By Matt Smith, Olympus Surgical Industrial America Inc.
  8. Article: Night-Vision Camera Combines Thermal And Low-Light-Level Images 8/26/2008
    Even on moonless but starlit nights, highly sensitive InGaAs cameras still produce good images for short-wavelength infrared. By thinning the image sensor chip and with illumination right through the substrate, the wavelength range of the detectors can be extended into the visible spectrum to then span 400 – 1700 nm. Together with uncooled microbolometer arrays for long-wavelength infrared, this allows the design of universal analysis tools which can take advantage of the fusion of optical and thermal images
